Texture shredding? Never encountered this before in low or high res renders.
Are you talking about the banded effect on your characters breast in the last pic you posted? I could be way off the mark here, but I'd say that could be the result of a poorly biased or low sized shadowmap or AO (?).

Interested to find out more about texture shredding if P7 does this.
